CLOSURE.

SPECIFICATION forming part of Letters Patent No. 750,257, dated January26, 1904.

Application filed October 14:, 1902. Renewed May 13,1903. Serial No.157,024. (No model.)

To all whom it may concern:

Be it known that I, EARLE E. CHAPMAN, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inClosures; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to 1b which it appertains to make and use the same.

This invention relates to means for preventing the fraudulent refillingof vessels, and particularly to closures for vessels; and some of theobjects of the invention are to provide a I 5 cheap and eflicient deviceof this character.

' Another object of the invention is to provide a closure which can onlybe removed without injury by being twisted or rotated upon the vesselinto a predetermined position.

With these and other objects in view the invention consists,essentially, in the construction, combination, and arrangement of partssubstantially as more fully described in the following specification andas illustrated in the 2 5 accompanying drawings, forming part of thisapplication, in which Figure 1 is a longitudinal sectional view of aform of closure employed. Fig. 2 is a bottom plan view of the same. Fig.3 is a top plan view of a vessel constructed with externalreceiving-recesses. Fig. 4 is a longitudinal central sectional View of aportion of a neck of a vessel. tional view of a modified form ofclosure.

3 5 Fig. 6 is a bottom plan view of the same. Fig. 7 is a top plan viewof a neck of a vessel having internal receiving-recesses. Fig. 8 is alongitudinal central sectional view of a portion of a neck of a vesselhaving internal re- 4 cesses, and Fig. 9 is a longitudinal centralsectional view of still another form of closure.

Similar characters of reference designate corresponding parts throughoutthe several views.

Referring to the drawings, and particularly to the constructionillustrated in Figs. 1, 2, 3, and 4 thereof, the reference character 1designates a cap or cover, which may be of any Fig. 5.is a longitudinalsec suitable form of construction and may be either plain or ornamented,and within the cap or cover is secured a disk 2, of cork or otherexpansible substance, to make a tight connection when the cover isforced down into position upon the neck of the vessel, as will bereadily understood. Formed on or connected with the inner surface of thecap or cover are resilient arms or engaging projections 3, preferablyextending upwardly and inwardly, substantially as shown in Figs. 1 and 2of the drawings, and constructed 'to engage or enter therecelving-recesses 4 upon the exterior of the neck of the vessel 5. Thereceiving-re cesses 4C are preferably segmental in crosssection andterminate upon the edges or circumference of the vessel-neck in plane orflat surfaces 6, Fig. 3, so that the closure may be removed Withoutbreaking or injuring the same by forcing the engaging projections 3 uponsaid fiat or plane surfaces 6 and then pulling off the cap or cover.

The operation of this invention will be readily understood from theforegoing description when taken in connection with the accompanyingdrawings and the following explana tion thereof.

After the vessel shall have been filled a cork or other disk is placedin the top of the cap or cover and the latter is forced down upon theneck of the vessel until the resilient projections 3 enter thereceiving-recesses 4 in the vessel-neck, whereupon the vessel issecurely sealed, and the cap or cover cannot be removed without injuryby force exerted along the longitudinal axis of the vessel; but when itis desired to remove the cap or cover without in,- jury it is onlynecessary to twister rotate the same upon the neck of. a vessel untilthe resilient projections 3 mountj'upon the flat or plane surfaces 6 onthe neck of the vessel, which will be accomplished by the curved bottomof the recesses,whereupon the cap or cover can be at once pulled off byforce exerted in a line with the longitudinal axis of the vessel.

Referring now to Figs. 5, 6, 7, and 8, the invention is illustratedapplied to a vessel having internal receiving-recesses and a plug orstopper having exterior engaging projections to enter said recesses. Inthis construction a vessel 5 is preferably provided with a plurality ofreceiving-recesses 4:; but in this instance the recesses are formed uponthe internal surface of the vessel-neck, and said recesses areconstructed to be engaged by the resilient engaging projections 3 upon aplug or stopper 7 preferably having a hollow bore or hollow centralportion 8 and a laterallyextending rim or flange 9, below which may besecured a ring of cork or other material 10 to afford a tight connectionwhen the closure is in position in the neck of the vessel. Formed on orconnected with the plug orstopper 7 are a plurality of resilientengaging projections 3, constructed to enter the receiving-recesses whena closure is forced into position, substantially as before explained.

The operation of the construction illustrated in Figs. 5, 6, 7 and 8 issubstantially similar to that hereinbefore described and shown, andfurther explanation thereof will not be required further than to saythat the plug or stopper 7 enters within the neck of the vessel, and theresilient projections 3 enter the internal receiving-recesses i toretain the plug or stopper in position and are removed therefrom byrotating the stopper until the projections thereon enter upon the planeor flat surfaces 6 between said recesses, when the plug or stopper 7 canbe pulled from the vessel.

In Fig. 9 of the drawings there is illustrated a plug or stopper similarto that shown in Figs. 5 and 6, with the exception that the ring 10 isomitted and a long cork 11 is substituted, which may be forced into theneck of the vessel before or simultaneously with the introduction of theplug or stopper 7, and the operation of this construction is similar tothat described in connection with Figs. 5 to 8 of the drawings.

It is not desired to confine this invention to the specificconstruction, combination, and arrangement of parts herein shown anddescribed, and the right is reserved to make all such changes in andmodifications of the same as come within the spirit and scope of theinvention.

I claim 1. A closure provided with resilient engaging projections and avessel having receivingrecesses terminating in intermediate planesurfaces upon the circumference of the vesselneck, whereby saidprojections entersaid recesses to retain the parts in position, and arerotated upon said intermediate surfaces to permit the removal of theparts.

2. A closure provided with resilient engaging projections, a packingwithin the closure and a vessel having receiving-recesses terminating inintermediate circumferential surfaces, whereby the parts are connectedby the engagement of said projections within said recesses and may bedisconnected when the former are rotated upon said intermediate surface.

3. A closure provided with a cap or cover having internal engagingprojections and a vessel having recesses upon the exterior thereofterminating upon the circumference of said neck, whereby saidprojections enter said recesses to retain said parts together, and arerotated out of said recesses to permit the disengagement of the parts.

4. A closure provided with a cap or cover having engaging projections,an'expansible disk within said cover and a vessel having ex ternalreceiving-recesses terminating upon the circumference of the vessel,whereby the parts retained together while said projections are withinsaid recesses and may be disconnected when said projections are turnedout of said recesses.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, at Los Angeles, in the county ofLos Angeles and State of California, this 3d day of October, 1902.

EARLE E. CHAPMAN.
